Ive got a question when applying my manual override lever on my tekonsha p3 controller should my 5th wheels wheels lock up if controllr is set to 13v.... Ive had my brakes adjusted and inspected and I still cant get them to lock up to set my controller per the instructions and then back off to just before lock up.. Trailer weighs 11klbs

I just had them adjusted yesterday from my rv dealer... They said they were way out of adjustment but they are only a little bit better..


My guess the dealer still does not have them adjusted correctly.
They need to be adjusted to lockup and back off no more than 4 clicks. Otherwise you get what you got.

I have read increasing the wire size to the trailer brakes is the trick..

Mine dont lock up either on my p3.. My trailer weighs 5000 lbs.

and set too high when in boost mode in slow traffic you get that annoying trailer grab that makes truck dive at rear from trailer grabbing..

I set high and leave on b1

Some will, some won't. Depends on many variables. Mine never have, but it's pretty close.
